Bel-Ray EXS Synthetic — 2 weights
We hold Bel-Ray EXS Synthetic in exactly two weights, 10W-40 and 10W-50, across 4 part numbers. Which one you want is settled by your owner's manual, not by preference.

Every Bel-Ray EXS Synthetic bottle in this list states full synthetic on the product itself. Where a bottle does not state its base stock we leave the field blank rather than assume one.
Priced by weight: 10W-40 from $22.99 for the 1 L (2 sizes) and 10W-50 from $22.99 (2 sizes).
Per litre the spread inside this line is real: the 4 L in 10W-40 works out to $20.50 a litre, against $22.99 for the 1 L in 10W-40. If your engine takes more than a couple of litres, the larger bottle is the cheaper way to buy the same oil.
We carry 6 Bel-Ray lines in total — EXS Synthetic plus MC-4T, EXL Mineral, V-Twin, EXP and Thumper Racing. EXS Synthetic is the dearest of them, opening at $22.99. Comparing across them is a fair way to shop; comparing a Bel-Ray grade against the same grade from another maker is what the weight pages are for.
Bottle sizes in this line: 1 L and 4 L. All 4 are available now. Prices shown are ours and come from the catalog, not a list price.
